Case studies

Story hook

February 2023. A microwave-sized robot reaches the Mariana Trench — the deepest point on Earth — and films a plastic shopping bag drifting through the cold black water. The bag has travelled 11 kilometres down. Nobody dumped it there. It has sunk, over years, from a sea surface 1,500 kilometres away. Environmental ethics, once a seminar-room subject, has physical evidence now: human action has reached the physically furthest place on the planet. Nothing is "elsewhere" anymore.

January 2024. Madison Square Garden, New York. A 14-year-old girl is barred from entering a Disney Rockettes show. Why? A facial-recognition system deployed by venue-owner MSG Entertainment identified her as the daughter of a lawyer who works for a law firm currently suing MSG. The girl has done nothing wrong. The lawyer's family has been algorithmically banned. The American Civil Liberties Union files suit. AI ethics moves from textbook to family heartbreak.

Mid-2024. Bengaluru. Software engineers at a global IT services firm refuse to write cookie-tracking code for a client who plans to use it to circumvent EU GDPR. Their CTO threatens termination. A business-ethics dilemma — between employer compliance, client demand, and global regulatory standards — that engineering teams across India face weekly.

These three case studies are not isolated. They are the frontier zones where ethics in 2026 is being tested. GS-IV Section B has shifted visibly toward these themes in 2022-24. This unit is the operational toolkit.

Why this matters for UPSC

Case studies in environmental, AI, and business ethics have appeared in GS-IV in 2018, 2020, 2022, 2023, 2024 — with weighting increasing. The 2024 paper had two of six case studies in these domains. Interview boards ask candidates with engineering, IT, biology, or commerce backgrounds every single year about specific cases (Bhopal, Volkswagen, ChatGPT deployment, deepfakes, climate justice). Prelims occasionally tests anchor laws (Polluter Pays, Public Trust, DPDP).
